  • How can I restore the "auto" values with for list-style-type in nested unordered lists with CSS?

    - by Michael
    By default, an unstyled set of nested <ul> lists looks like this (in Chrome, Firefox, and IE at least): The top level has a list-style-type of disc, the next level is circle, and subsequent levels are square. If I include a stylesheet that changes the list-style-type to none, is there a simple way to revert back to the "automatic bullet types" later in the document? (e.g., override with a subsequent CSS definition or JavaScript style change) Basically, I'm looking for something like list-style-type: auto; (which is apparently not valid and has no effect): <style type="text/css"> ul { list-style-type: none; } ul { list-style-type: auto; } /* Does not work */ </style> Setting the list-style-type back to disc changes every bullet in the list and I no longer see different bullets at different levels, so that doesn't work either. Is the only way to accomplish this by explicitly defining styles for every level? e.g.: <style type="text/css"> ul { list-style-type: disc; } ul ul { list-style-type: circle; } ul ul ul { list-style-type: square; } </style>

  • Quick questions re moving to InfoPath forms

    - by sweissman
    Hi there: I’ve been asked to look into how best to move forms into InfoPath and have a couple of basic questions about your experiences so I can get an insider’s lay of the land. Even some short, quick bullets would be really helpful -- thank you! Are you starting from scratch in InfoPath, or are you converting from paper or a different e-format? (Jetform, PDF, etc.) Are you trying to re-create the layout of a specific paper form, or is a regular online form OK? (trying to learn what the latest thinking is about this) Do you need only simple fill and submit capabilities, or do you need programming for calculations, validation, database lookup/entry/reporting, etc. as well? (don’t know how much harder it is to do all this vs. not) How long does each form take to finish? (I know it depends, but is there a rough guideline for planning purposes?) Who’s doing the actual work? (by title or function) What is especially straightforward or challenging about moving to InfoPath forms? (forewarned is forearmed!)

  • How to determine which enemy is hit and destroy it alone

    - by Jon Ferriter
    http://jsfiddle.net/5DB6K/ I have this game being made where you shoot enemies from the sides of the screen. I've got the bullets moving and being removed when they reach the end of the screen (if they didn't hit any enemy) and removing the enemy when they collide with it. //------------collision----------------// if(shot === true){ bulletY = $('.bullet').position().top + 2; bulletX = $('.bullet').position().left + 2; $('.enemy').each(function(){ if($('.enemy').hasClass('smallEnemy')){ enemyY = $(this).position().top + 7; enemyX = $(this).position().left + 7; if(Math.abs(bulletY - enemyY) <= 9 && Math.abs(bulletX - enemyX) <=9){ $(this).remove(); score = score + 40; bulletDestroy(); } } }); } However, the bullet destroys every enemy if the collision check is right which isn't what I want. I want to check if the enemy has the class of either smallEnemy, medEnemy, or lrgEnemy and then do the collision check which is what I thought I had but it doesn't seem to work. Also, the game starts to lag the more and more time goes on. Would anyone know the reason for that?

  • What presentation software suits my needs?

    - by claws
    Background: I'm teaching biology to 12th grade students. The syllabus I'm teaching is huge. I mean literally, very huge. There is a lot for students to remember. There are no less than 1000 facts (weird names, dates etc) for students to remember. They'll have to remember all of them, they don't have a choice. The notes I compiled for their learning itself is upto 80 printed pages(Just the bullet outline & facts). That's just one chapter. We have 34 chapters. Also my students are very hardworking, they study upto 8-10hrs per day (Yeah! we are from India :). So, I want to ensure maximum retaining by the students at each and every stage (Teaching & Learning). I'm trying to as many memory training techniques as possible. I'm trying to incorporate, mnemonics, strong visual aids (pictures, 3D-animations, real videos etc.), spaced repetition etc. I think MS powerpoint is not suitable for my needs: There are about 200 slides per chapter. Its very easy for students to get lost while teaching. Because the problem with powerpoint is that it gives facts (as bullets) but it doesn't exploit the association & organization (Concept Map) of the content, which helps students learn quickly. I found an amazing software called XMind. You can see the screenshot here. Problem is that it is not as powerpoint in terms of powerpoint. This software can be used for just for concept maps. In the above screenshot, each topic occupies a single slide. I have an Image/picture(Detailed huge picture) and about 5-10 bullet points and probably a video or an animation of somethings. And this XMind is not good at presenting, in terms that it doesn't allow me to set what to present after what. I want to present a top down view, with a slide for each topic. PS: I Don't like prezi.com. I tried but it simply is too confusing for my students. It zooms here and there. I didn't tried it but I've seen few presentations.

  • Inside Red Gate - Project teams

    - by Simon Cooper
    Within each division in Red Gate, development effort is structured around one or more project teams; currently, each division contains 2-3 separate teams. These are self contained units responsible for a particular development project. Project team structure The typical size of a development team varies, but is normally around 4-7 people - one project manager, two developers, one or two testers, a technical author (who is responsible for the text within the application, website content, and help documentation) and a user experience designer (who designs and prototypes the UIs) . However, team sizes can vary from 3 up to 12, depending on the division and project. As an rule, all the team sits together in the same area of the office. (Again, this is my experience of what happens. I haven't worked in the DBA division, and SQL Tools might have changed completely since I moved to .NET. As I mentioned in my previous post, each division is free to structure itself as it sees fit.) Depending on the project, and the other needs in the division, the tech author and UX designer may be shared between several projects. Generally, developers and testers work on one project at a time. If the project is a simple point release, then it might not need a UX designer at all. However, if it's a brand new product, then a UX designer and tech author will be involved right from the start. Developers, testers, and the project manager will normally stay together in the same team as they work on different projects, unless there's a good reason to split or merge teams for a particular project. Technical authors and UX designers will normally go wherever they are needed in the division, depending on what each project needs at the time. In my case, I was working with more or less the same people for over 2 years, all the way through SQL Compare 7, 8, and Schema Compare for Oracle. This helped to build a great sense of camaraderie wihin the team, and helped to form and maintain a team identity. This, in turn, meant we worked very well together, and so the final result was that much better (as well as making the work more fun). How is a project started and run? The product manager within each division collates user feedback and ideas, does lots of research, throws in a few ideas from people within the company, and then comes up with a list of what the division should work on in the next few years. This is split up into projects, and after each project is greenlit (I'll be discussing this later on) it is then assigned to a project team, as and when they become available (I'm sure there's lots of discussions and meetings at this point that I'm not aware of!). From that point, it's entirely up to the project team. Just as divisions are autonomous, project teams are also given a high degree of autonomy. All the teams in Red Gate use some sort of vaguely agile methodology; most use some variations on SCRUM, some have experimented with Kanban. Some store the project progress on a whiteboard, some use our bug tracker, others use different methods. It all depends on what the team members think will work best for them to get the best result at the end. From that point, the project proceeds as you would expect; code gets written, tests pass and fail, discussions about how to resolve various problems are had and decided upon, and out pops a new product, new point release, new internal tool, or whatever the project's goal was. The project manager ensures that everyone works together without too much bloodshed and that thrown missiles are constrained to Nerf bullets, the developers write the code, the testers ensure it actually works, and the tech author and UX designer ensure that people will be able to use the final product to solve their problem (after all, developers make lousy UI designers and technical authors). Projects in Red Gate last a relatively short amount of time; most projects are less than 6 months. The longest was 18 months. This has evolved as the company has grown, and I suspect is a side effect of the type of software Red Gate produces. As an ISV, we sell packaged software; we only get revenue when customers purchase the ready-made tools. As a result, we only get a sellable piece of software right at the end of a project. Therefore, the longer the project lasts, the more time and money has to be invested by the company before we get any revenue from it, and the riskier the project becomes. This drives the average project time down. Small project teams are the core of how Red Gate produces software, and are what the whole development effort of the company is built around. In my next post, I'll be looking at the office itself, and how all 200 of us manage to fit on two floors of a small office building.

  • Top ten things that don't make sense in The Walking Dead

    - by iamjames
    For those of you that don't know, The Walking Dead is a popular American TV show on AMC about a group of people trying to survive in a zombie-filled world.Here's the top ten eleven things that don't make sense on the show (and have never been explained) 1)  They never visit stores.  No Walmarts, Kmarts, Targets, shopping malls, pawn shops, gas stations, etc.  You'd think that would be the first place you'd visit for supplies, but they never have.  Not once.  There was a tiny corner store they visited in a small town, and while many products were already gone they did find several useful items.  2)  They never raid houses.  Why not?  One would imagine that they would want to search houses for useful items, but they don't.3)  They don't use 2 way radios.  Modern 2-way radios have a 36-mile range.  That's probably best possible range, but even if the range is only 10% of that, 3.6 miles, that's still more than enough for most situations, for the occasional "hey zombies attacking can you give me a hand?" or "there's zombies walking by stay inside until they leave" or "remember to pick up milk at the store love mom".  And yes they would need batteries or recharging, but they have been using gas-powered generators on the show and I'm sure a car charger would work.4)  They use gas-guzzling vehicles.  Every vehicle they have is from the 80s or 90s except for the new Kia SUV there for product placement.  Why?  They should all be driving new small SUVs or hybrids.  Visit a dealership and steal more fuel-efficient vehicles, because while the Walmart's might be empty from people raiding them for supplies, I'm sure most people weren't thinking "Gee, I should go car shopping" when the infection hit5)  They drive a motorcycle.  Seriously?  Let's find the least protective vehicle and drive that.  And while motorcycles get reasonable gas mileage, 5 people in a SUV gets better gas mileage per person than 5 people all driving motorcycles so it doesn't make economical sense either.6)  They drive loud vehicles.  The motorcycle used is commonly referred to as a chopper and is about as loud as a motorcycle can get.  The zombies are attracted to loud noise, so wouldn't it make more sense to drive vehicles that makes less sound?  Because as soon as you stop the bike and get off you're surrounded by zombies that heard you coming.  And it's not just the bike, the ~1980s Chevy SUV in the show is also very loud.7)  They never run out of food.  Seems like that would be a almost daily struggle, keeping enough food available for about a dozen people, yet I've never seen them visit a grocery store or local convenience store to stock up.8)  They don't carry swords, machetes, clubs, etc.  Let's face it, biting is not a very effective means of attack.  It's good for animals because they have fangs and little else, but humans have been finding better ways of killing each other since forever.  So why doesn't everyone on the show carry a sword or machete or at least a baseball bat?  Anything is better than wasting valuable bullets all the time.  Sure, dozen zombies approaching?  Shoot them.  One zombie approaching?  Save the bullet, cut off it's head.  9)  They do not wear protective clothing.  Human teeth are not exactly the sharpest teeth in the animal kingdom.  The leather shoes your dog ripped to shreds within minutes would probably take you days to bite through.  So why do they walk around half-naked?  Yes I know it's hot in Atlanta, but you'd think they'd at least have some tough leather coats or something for protection.  Maybe put a few small vent holes in the fabric if it's really hot.  Or better:  make your own chainmail.  Chainmail was used for thousands of years for protection from swords and is still used by scuba divers for protection from sharks.  If swords and sharks can't puncture it, human teeth don't stand a chance.  10)  They don't build barricades or dig trenches around properties.  In Season 2 they stayed at a farm in the middle of no where.  While being far away from people is a great way to stay far away from zombies, it would still make sense to build some sort of defenses.  Hordes of zombies would knock down almost any fence, but what about a trench or moat?  Maybe something not too wide so it can be jumped over easily but a zombie would fall into because I haven't seen too many jumping zombies on the show.  11)  They don't live in a mall or tall office building.  A mall would be perfect.  They have large security gates designed to keep even hundreds of people from breaking in and offer lots of supplies and food.  They're usually hundreds of thousands of square feet and fully enclosed, one could probably live their entire life happily in a mall.  Tall office building with on-site cafeteria would be another good choice.  They also usually offer good security and office furniture could be pushed out of the windows to crush approaching zombies, and the cafeteria is usually stocked to provide food for hundreds or thousands of office workers so food wouldn't be a problem for a long time. So there you have it, eleven things that don't make sense in The Walking Dead.  Have any of your own you'd like to add or were one of these things covered in the show?  Let me know in the comments.

  • Collision Error

    - by Manji
    I am having trouble with collision detection part of the game. I am using touch events to fire the gun as you will see in the video. Note, the android icon is a temporary graphic for the bullets When ever the user touches (represented by clicks in the video)the bullet appears and kills random sprites. As you can see it never touches the sprites it kills or kill the sprites it does touch. My Question is How do I fix it, so that the sprite dies when the bullet hits it? Collision Code snippet: //Handles Collision private void CheckCollisions(){ synchronized(mSurfaceHolder){ for (int i = sprites.size() - 1; i >= 0; i--){ Sprite sprite = sprites.get(i); if(sprite.isCollision(bullet)){ sprites.remove(sprite); mScore++; if(sprites.size() == 0){ mLevel = mLevel +1; currentLevel++; initLevel(); } break; } } } } Sprite Class Code Snippet: //bounding box left<right and top>bottom int left ; int right ; int top ; int bottom ; public boolean isCollision(Beam other) { // TODO Auto-generated method stub if(this.left>other.right || other.left<other.right)return false; if(this.bottom>other.top || other.bottom<other.top)return false; return true; } EDIT 1: Sprite Class: public class Sprite { // direction = 0 up, 1 left, 2 down, 3 right, // animation = 3 back, 1 left, 0 front, 2 right int[] DIRECTION_TO_ANIMATION_MAP = { 3, 1, 0, 2 }; private static final int BMP_ROWS = 4; private static final int BMP_COLUMNS = 3; private static final int MAX_SPEED = 5; private HitmanView gameView; private Bitmap bmp; private int x; private int y; private int xSpeed; private int ySpeed; private int currentFrame = 0; private int width; private int height; //bounding box left<right and top>bottom int left ; int right ; int top ; int bottom ; public Sprite(HitmanView gameView, Bitmap bmp) { this.width = bmp.getWidth() / BMP_COLUMNS; this.height = bmp.getHeight() / BMP_ROWS; this.gameView = gameView; this.bmp = bmp; Random rnd = new Random(); x = rnd.nextInt(gameView.getWidth() - width); y = rnd.nextInt(gameView.getHeight() - height); xSpeed = rnd.nextInt(MAX_SPEED * 2) - MAX_SPEED; ySpeed = rnd.nextInt(MAX_SPEED * 2) - MAX_SPEED; } private void update() { if (x >= gameView.getWidth() - width - xSpeed || x + xSpeed <= 0) { xSpeed = -xSpeed; } x = x + xSpeed; if (y >= gameView.getHeight() - height - ySpeed || y + ySpeed <= 0) { ySpeed = -ySpeed; } y = y + ySpeed; currentFrame = ++currentFrame % BMP_COLUMNS; } public void onDraw(Canvas canvas) { update(); int srcX = currentFrame * width; int srcY = getAnimationRow() * height; Rect src = new Rect(srcX, srcY, srcX + width, srcY + height); Rect dst = new Rect(x, y, x + width, y + height); canvas.drawBitmap(bmp, src, dst, null); } private int getAnimationRow() { double dirDouble = (Math.atan2(xSpeed, ySpeed) / (Math.PI / 2) + 2); int direction = (int) Math.round(dirDouble) % BMP_ROWS; return DIRECTION_TO_ANIMATION_MAP[direction]; } public boolean isCollision(float x2, float y2){ return x2 > x && x2 < x + width && y2 > y && y2 < y + height; } public boolean isCollision(Beam other) { // TODO Auto-generated method stub if(this.left>other.right || other.left<other.right)return false; if(this.bottom>other.top || other.bottom<other.top)return false; return true; } } Bullet Class: public class Bullet { int mX; int mY; private Bitmap mBitmap; //bounding box left<right and top>bottom int left ; int right ; int top ; int bottom ; public Bullet (Bitmap mBitmap){ this.mBitmap = mBitmap; } public void draw(Canvas canvas, int mX, int mY) { this.mX = mX; this.mY = mY; canvas.drawBitmap(mBitmap, mX, mY, null); } }

  • Editing Neo Slider to move in one direction

    - by user2106416
    I have a website with brandspace theme from pixelentity. Currently, the slider move from right to left ( auto transition) . But, when the slider reaches the last image, it will go back to the first image by making all previous images sliding back from left to right. I want to make the slider to have a normal transition,i.e. going back to first image but still with the image sliding from right to left. Below is the slider.php code.: <?php $t =& peTheme(); ?> <?php list($pid,$conf,$loop) = $t->template->data(); ?> <?php $w = $t->media->width(940); ?> <?php $h = $t->media->height(300); ?> <div class="peSlider peVolo" data-autopause="disabled" data-plugin="<?php echo apply_filters("pe_theme_slider_plugin","peVolo"); ?>" data-controls-arrows="edges-full" data-controls-bullets="disabled" data-icon-font="enabled"> <?php while ($slide =& $loop->next()): ?> <?php $link = empty($slide->link) ? false: $slide->link; ?> <?php $img = $t->image->resizedImg($slide->img,$w,$h); ?> <div data-delay="4" <?php echo $slide->idx == 0 ?

  • How can I stop Flash from changing indent when user Clicks on hyperlink in TextField?

    - by Paul Chernoch
    I have a TextField which I initialize by setting htmlText. The text has anchor tags (hyperlinks). When a user clicks on the hyperlink, the indentation of the second and subsequent lines in the paragraph changes. Why? How do I stop it? My html has an image at the beginning of the line, followed by the tag, followed by more text. To style the hyper links to look blue always and underlined when the mouse is over them, I do this: var css:StyleSheet = new StyleSheet(); css.parseCSS("a {color: #0000FF;} a:hover {text-decoration: underline;}"); stepText.styleSheet = css; stepText.htmlText = textToUse; stepText.visible = true; Here is a fragment of the html text (with newlines and exrta whitespace added to improve readability - originally it was one long line): <textformat indent="-37" blockindent="37" > <img src="media/interface/level-1-bullets/solid-circle.png" align="left" hspace="8" vspace="1"/> American Dental Association. (n.d.). <i>Cleaning your teeth and gums (oral hygiene)</i>. Retrieved 11/24/08, from <a href="http://www.ada.org/public/topics/cleaning_faq.asp" target="_blank">http://www.ada.org/public/topics/cleaning_faq.asp </a> </textformat> <br/> As it turns out, the text field is of a width such that it wraps and the second line starts with "Retrieved 11/24/08". Clicking on the hyper link causes this particular line to be indented. Subsequent paragraphs are not affected. ASIDE: The image is a list bullet about 37 pixels wide. (I used images instead of li tags because Flash does not allow nested lists, so I faked it using a series of images with varying amounts of whitespace to simulate three levels of indentation.) IDEA: I was thinking of changing all hyperlinks to use "event:" as the URL protocol, which causes a TextEvent.LINK event to be triggered instead of following the link. Then I would have to open the browser in a second call. I could use this event handler to set the html text to itself, which might clear the problem. (When I switch pages in my application and then come back to the page, everything is OKAY again.) PROBLEM: If I use the "event:" protocol and user tries the right-mouse button click, they will get an error, or so I am told. (See http://www.blog.lessrain.com/as3-texteventlink-and-contextmenu-incompatibilities/ ) I do not like this trade-off.

  • iOS dynamic object creation

    - by Abdul Ahmad
    I've worked with Xcode and iOS on a few personal projects and have always used non-object-oriented designs for everything... just because I've been doing mostly learning/experimenting with things. Now I've been trying to implement some object oriented design into one game I've made previously. The idea is, I have a space ship that can shoot bullets. In the past I basically added the UIImageView to the storyboard and then connected it to the .h file and from there did things on it like move it around or whatever (using CGPointMake). The idea now is to make a method (and a whole other class soon) that will create a UIImageView programmatically, allocate it, add it to the superview etc... I've got this working so far, easy stuff, but the next part is a bit harder. Where do I store this local variable "bullet"? I've been saving it to an NSMutableArray and doing the following: (actually here are the methods that I have) -(void)movement { for (int i = 0; i < [array1 count]; i ++) { UIImageView *a = [array1 objectAtIndex:i]; a.center = CGPointMake(a.center.x + 2, a.center.y); if (a.center.x > 500) { [array1 removeObjectAtIndex:i]; [a removeFromSuperview]; } } } -(void)getBullet { UIImageView *bullet = [[UIImageView alloc] initWithFrame:CGRectMake(ship.center.x + 20, ship.center.y - 2, 15, 3)]; bullet.image = [UIImage imageNamed:@"bullet2.png"]; bullet.hidden = NO; [self.view addSubview:bullet]; [array1 addObject:bullet]; } (by the way, array1 is declared in the .h file) and theres a timer that controls the movement method timer = [NSTimer scheduledTimerWithTimeInterval:0.5 target:self selector:@selector(movement) userInfo:nil repeats:YES]; first question is: what is the correct way of doing this? Storing a bullet for example until it is removed from the superview, should I store it another way? and another question is, when I remove a UIImageView from the superview, does that remove it from memory so its not using up system resources? Thank you for the help! (will update if I Think of other questions

  • Creating a multi-column rollover image gallery with HTML 5

    - by nikolaosk
    I know it has been a while since I blogged about HTML 5. I have two posts in this blog about HTML 5. You can find them here and here.I am creating a small content website (only text,images and a contact form) for a friend of mine.He wanted to create a rollover gallery.The whole concept is that we have some small thumbnails on a page, the user hovers over them and they appear enlarged on a designated container/placeholder on a page. I am trying not to use Javascript scripts when I am using effects on a web page and this is what I will be doing in this post.  Well some people will say that HTML 5 is not supported in all browsers. That is true but most of the modern browsers support most of its recommendations. For people who still use IE6 some hacks must be devised.Well to be totally honest I cannot understand why anyone at this day and time is using IE 6.0.That really is beyond me.Well, the point of having a web browser is to be able to ENJOY the great experience that the WE? offers today.  Two very nice sites that show you what features and specifications are implemented by various browsers and their versions are http://caniuse.com/ and http://html5test.com/. At this times Chrome seems to support most of HTML 5 specifications.Another excellent way to find out if the browser supports HTML 5 and CSS 3 features is to use the Javascript lightweight library Modernizr.In this hands-on example I will be using Expression Web 4.0.This application is not a free application. You can use any HTML editor you like.You can use Visual Studio 2012 Express edition. You can download it here. In order to be absolutely clear this is not (and could not be ) a detailed tutorial on HTML 5. There are other great resources for that.Navigate to the excellent interactive tutorials of W3School.Another excellent resource is HTML 5 Doctor.For the people who are not convinced yet that they should invest time and resources on becoming experts on HTML 5 I should point out that HTML 5 websites will be ranked higher than others. Search engines will be able to locate better the content of our site and its relevance/importance since it is using semantic tags. Let's move now to the actual hands-on example. In this case (since I am mad Liverpool supporter) I will create a rollover image gallery of Liverpool F.C legends. I create a folder in my desktop. I name it Liverpool Gallery.Then I create two subfolders in it, large-images (I place the large images in there) and thumbs (I place the small images in there).Then I create an empty .html file called LiverpoolLegends.html and an empty .css file called style.css.Please have a look at the HTML Markup that I typed in my fancy editor package below<!doctype html><html lang="en"><head><title>Liverpool Legends Gallery</title><meta charset="utf-8"><link rel="stylesheet" type="text/css" href="style.css"></head><body><header><h1>A page dedicated to Liverpool Legends</h1><h2>Do hover over the images with the mouse to see the full picture</h2></header><ul id="column1"><li><a href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=8927200#"><img src="thumbs/john-barnes.jpg" alt=""><img class="large" src="large-images/john-barnes-large.jpg" alt=""></a></li><li><a href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=8927200#"><img src="thumbs/ian-rush.jpg" alt=""><img class="large" src="large-images/ian-rush-large.jpg" alt=""></a></li><li><a href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=8927200#"><img src="thumbs/graeme-souness.jpg" alt=""><img class="large" src="large-images/graeme-souness-large.jpg" alt=""></a></li></ul><ul id="column2"><li><a href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=8927200#"><img src="thumbs/steven-gerrard.jpg" alt=""><img class="large" src="large-images/steven-gerrard-large.jpg" alt=""></a></li><li><a href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=8927200#"><img src="thumbs/kenny-dalglish.jpg" alt=""><img class="large" src="large-images/kenny-dalglish-large.jpg" alt=""></a></li><li><a href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=8927200#"><img src="thumbs/robbie-fowler.jpg" alt=""><img class="large" src="large-images/robbie-fowler-large.jpg" alt=""></a></li></ul><ul id="column3"><li><a href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=8927200#"><img src="thumbs/alan-hansen.jpg" alt=""><img class="large" src="large-images/alan-hansen-large.jpg" alt=""></a></li><li><a href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=8927200#"><img src="thumbs/michael-owen.jpg" alt=""><img class="large" src="large-images/michael-owen-large.jpg" alt=""></a></li></ul></body></html> It is very easy to follow the markup. Please have a look at the new doctype and the new semantic tag <header>. I have 3 columns and I place my images in there.There is a class called "large".I will use this class in my CSS code to hide the large image when the mouse is not on (hover) an image Make sure you validate your HTML 5 page in the validator found hereHave a look at the CSS code below that makes it all happen.img { border:none;}#column1 { position: absolute; top: 30; left: 100; }li { margin: 15px; list-style-type:none;}#column1 a img.large {  position: absolute; top: 0; left:700px; visibility: hidden;}#column1 a:hover { background: white;}#column1 a:hover img.large { visibility:visible;}#column2 { position: absolute; top: 30; left: 195px; }li { margin: 5px; list-style-type:none;}#column2 a img.large { position: absolute; top: 0; left:510px; margin-left:0; visibility: hidden;}#column2 a:hover { background: white;}#column2 a:hover img.large { visibility:visible;}#column3 { position: absolute; top: 30; left: 400px; width:108px;}li { margin: 5px; list-style-type:none;}#column3 a img.large { width: 260px; height:260px; position: absolute; top: 0; left:315px; margin-left:0; visibility: hidden;}#column3 a:hover { background: white;}#column3 a:hover img.large { visibility:visible;}?n the first line of the CSS code I set the images to have no border.Then I place the first column in the page and then remove the bullets from the list elements.Then I use the large CSS class to create a position for the large image and hide it.Finally when the hover event takes place I make the image visible.I repeat the process for the next two columns. I have tested the page with IE 10 and the latest versions of Opera,Chrome and Firefox.Feel free to style your HTML 5 gallery any way you want through the magic of CSS.I did not bother adding background colors and borders because that was beyond the scope of this post. Hope it helps!!!!

  • From J2EE to Java EE: what has changed?

    - by Bruno.Borges
    See original @Java_EE tweet on 29 May 2014 Yeap, it has been 8 years since the term J2EE was replaced, and still some people refer to it (mostly recruiters, luckily!). But then comes the question: what has changed besides the name? Our community friend Abhishek Gupta worked on this question and provided an excellent response titled "What's in a name? Java EE? J2EE?". But let me give you a few highlights here so you don't lose yourself with YATO (yet another tab opened): J2EE used to be an infrastructure and resources provider only, requiring developers to depend on external 3rd-party frameworks to then implement application requirements or improve productivity J2EE used to require hundreds of XML lines of codes to define just a dozen of resources like EJBs, MDBs, Servlets, and so on J2EE used to support only EAR (Enterprise Archives) with a bunch of other archives like JARs and WARs just to run a simple Web application And so on, and so on! It was a great technology but still required a lot of work to get something up and running. Remember xDoclet? Remember Struts? The old days of pure Hibernate code? Or when Ajax became a trending topic and we were all implementing it with DWR Servlet? Still, we J2EE developers survived, and learned, and helped evolve the platform to a whole new level of DX (Developer Experience). A new DX for J2EE suggested a new name. One that referred to the platform as the Enterprise Edition of Java, because "Java is why we're here" quoting Bill Shannon. The release of Java EE 5 included so many features that clearly showed developers the platform was going after all those DX gaps. Radical simplification of the persistence model with the introduction of JPA Support of Annotations following the launch of Java SE 5.0 Updated XML APIs with the introduction of StAX Drastic simplification of the EJB component model (with annotations!) Convention over Configuration and Dependency Injection A few bullets you may say but that represented a whole new DX and a vision for upcoming versions. Clearly, the release of Java EE 5 helped drive the future of the platform by reducing the number of XMLs, Java Interfaces, simplified configurations, provided convention-over-configuration, etc! We then saw the release of Java EE 6 with even more great features like Managed Beans, CDI, Bean Validation, improved JSP and Servlets APIs, JASPIC, the posisbility to deploy plain WARs and so many other improvements it is difficult to list in one sentence. And we've gotta give Spring Framework some credit here: thanks to Rod Johnson and team, concepts like Dependency Injection fit perfectly into the Java EE Platform. Clearly, Spring used to be one of the most inspiring frameworks for the Java EE platform, and it is great to see things like Pivotal and Spring supporting JSR 352 Batch API standard! Cooperation to keep improving DX at maximum in the server-side Java landscape.  The master piece result of these previous releases is seen and called today as Java EE 7, which by providing a newly and improved JavaServer Faces release, with new features for Web Development like WebSockets API, improved JAX-RS, and JSON-P, but also including Batch API and so many other great improvements, has increased developer productivity and brought innovation to server-side Java developers. Java EE is not just a new name (which was introduced back in May 2006!) but a new Developer Experience for server-side Java developers. To show you why we are here and where we are going (see the Java EE 8 update), we wanted to share with you a draft of the new Java EE logos that the evangelist team created, to help you spread the word about Java EE. You can get access to these images at the Java EE Platform Facebook Album, or the Google+ Java EE Platform Album whichever is better for you, but don't forget to like and/or +1 those social network profiles :-) A message to all job recruiters: stop using J2EE and start using Java EE if you want to find great Java EE 5, Java EE 6, or Java EE 7 developers To not only save you recruiter valuable characters when tweeting that job opportunity but to also match the correct term, we invite you to replace long terms like "Java/J2EE" or even worse "#Java #J2EE #JEE" or all these awkward combinations with the only acceptable hashtag: #JavaEE. And to prove that Java EE is catching among developers and even recruiters, and that J2EE is past, let me highlight here how are the jobs trends! The image below is from Indeed.com trends page, for the following keywords: J2EE, Java/J2EE, Java/JEE, JEE. As you can see, J2EE is indeed going away, while JEE saw some increase. Perhaps because some people are just lazy to type "Java" but at the same time they are aware that J2EE (the '2') is past. We shall forgive that for a while :-) Another proof that J2EE is going away is by looking at its trending statistics at Google. People have been showing less and less interest in the term J2EE. See the chart below:  Recruiter, if you still need proof that J2EE is past, that Java EE is trending, and that other job recruiters are seeking for Java EE developers, and that the developer community is aware of the new term, perhaps these other charts can show you what term you should be using. See for example the Job Trends for Java EE at Indeed.com and notice where it started... 2006! 8 years ago :-) Last but not least, the Google Trends for Java EE term (including the still wrong but forgivable JavaEE term) shows us that the new term is catching up very well. J2EE is past. Oh, and don't worry about the curves going down. We developers like to be hipsters sometimes and today only AngularJS, NodeJS, BigData are going up. Java EE and other traditional server-side technologies such as Spring, or even from other platforms such as Ruby on Rails, PHP, Grails, are pretty much consolidated and the curves... well, they are consolidated too. So If you are a Java EE developer, drop that J2EE from your résumé, and let recruiters also know that this term is past. Embrace Java EE, and enjoy a new developer experience for server-side Java developers. Java EE on TwitterJava EE on Google+Java EE on Facebook

  • Going Paperless

    - by Jesse
    One year ago I came to work for a company where the entire development team is 100% “remote”; we’re spread over 3 time zones and each of us works from home. This seems to be an increasingly popular way for people to work and there are many articles and blog posts out there enumerating the advantages and disadvantages of working this way. I had read a lot about telecommuting before accepting this job and felt as if I had a pretty decent idea of what I was getting into, but I’ve encountered a few things over the past year that I did not expect. Among the most surprising by-products of working from home for me has been a dramatic reduction in the amount of paper that I use on a weekly basis. Hoarding In The Workplace Prior to my current telecommute job I worked in what most would consider pretty traditional office environments. I sat in cubicles furnished with an enormous plastic(ish) modular desks, had a mediocre (at best) PC workstation, and had ready access to a seemingly endless supply of legal pads, pens, staplers and paper clips. The ready access to paper, countless conference room meetings, and abundance of available surface area on my desk and in drawers created a perfect storm for wasting paper. I brought a pad of paper with me to every meeting I ever attended, scrawled some brief notes, and then tore that sheet off to keep next to my keyboard to follow up on any needed action items. Once my immediate need for the notes was fulfilled, that sheet would get shuffled off into a corner of my desk or filed away in a drawer “just in case”. I would guess that for all of the notes that I ever filed away, I might have actually had to dig up and refer to 2% of them (and that’s probably being very generous). That said, on those rare occasions that I did have to dig something up from old notes, it was usually pretty important and I ended up being very glad that I saved them. It was only when I would leave a job or move desks that I would finally gather all those notes together and take them to shredding bin to be disposed of. When I left my last job the amount of paper I had accumulated over my three years there was absurd, and I knew coworkers who had substance-abuse caliber paper wasting addictions that made my bad habit look like nail-biting in comparison. A Product Of My Environment I always hated using all of this paper, but simply couldn’t bring myself to stop. It would look bad if I showed up to an important conference room meeting without a pad of paper. What if someone said something profound! Plus, everyone else always brought paper with them. If you saw someone walking down the hallway with a pad of paper in hand you knew they must be on their way to a conference room meeting. Some people even had fancy looking portfolio notebook sheaths that gave their legal pads all the prestige of a briefcase. No one ever worried about running out of fresh paper because there was an endless supply, and there certainly was no shortage of places to store and file used paper. In short, the traditional office was setup for using tons and tons of paper; it’s baked into the culture there. For that reason, it didn’t take long for me to kick the paper habit once I started working from home. In my home office, desk and drawer space are at a premium. I don’t have the budget (or the tolerance) for huge modular office furniture in my spare bedroom. I also no longer have access to a bottomless pit of office supplies stock piled in cabinets and closets. If I want to use some paper, I have to go out and buy it. Finally (and most importantly), all of the meetings that I have to attend these days are “virtual”. We use instant messaging, VOIP, video conferencing, and e-mail to communicate with each other. All I need to take notes during a meeting is my computer, which I happen to be sitting right in front of all day. I don’t have any hard numbers for this, but my gut feeling is that I actually take a lot more notes now than I ever did when I worked in an office. The big difference is I don’t have to use any paper to do so. This makes it far easier to keep important information safe and organized. The Right Tool For The Job When I first started working from home I tried to find a single application that would fill the gap left by the pen and paper that I always had at my desk when I worked in an office. Well, there are no silver bullets and I’ve evolved my approach over time to try and find the best tool for the job at hand. Here’s a quick summary of how I take notes and keep everything organized. Notepad++ – This is the first application I turn to when I feel like there’s some bit of information that I need to write down and save. I use Launchy, so opening Notepad++ and creating a new file only takes a few keystrokes. If I find that the information I’m trying to get down requires a more sophisticated application I escalate as needed. The Desktop – By default, I save every file or other bit of information to the desktop. Anyone who has ever had to fix their parents computer before knows that this is a dangerous game (any file my mother has ever worked on is saved directly to the desktop and rarely moves anywhere else). I agree that storing things on the desktop isn’t a great long term approach to keeping organized, which is why I treat my desktop a bit like my e-mail inbox. I strive to keep both empty (or as close to empty as I possibly can). If something is on my desktop, it means that it’s something relevant to a task or project that I’m currently working on. About once a week I take things that I’m not longer working on and put them into my ‘Notes’ folder. The ‘Notes’ Folder – As I work on a task, I tend to accumulate multiple files associated with that task. For example, I might have a bit of SQL that I’m working on to gather data for a new report, a quick C# method that I came up with but am not yet ready to commit to source control, a bulleted list of to-do items in a .txt file, etc. If the desktop starts to get too cluttered, I create a new sub-folder in my ‘Notes’ folder. Each sub-folder’s name is the current date followed by a brief description of the task or project. Then all files related to that task or project go into that sub folder. By using the date as the first part of the folder name, these folders are automatically sorted in reverse chronological order. This means that things I worked on recently will generally be near the top of the list. Using the built-in Windows search functionality I now have a pretty quick and easy way to try and find something that I worked on a week ago or six months ago. Dropbox – Dropbox is a free service that lets you store up to 2GB of files “in the cloud” and have those files synced to all of the different computers that you use. My ‘Notes’ folder lives in Dropbox, meaning that it’s contents are constantly backed up and are always available to me regardless of which computer I’m using. They also have a pretty decent iPhone application that lets you browse and view all of the files that you have stored there. The free 2GB edition is probably enough for just storing notes, but I also pay $99/year for the 50GB storage upgrade and keep all of my music, e-books, pictures, and documents in Dropbox. It’s a fantastic service and I highly recommend it. Evernote – I use Evernote mostly to organize information that I access on a fairly regular basis. For example, my Evernote account has a running grocery shopping list, recipes that my wife and I use a lot, and contact information for people I contact infrequently enough that I don’t want to keep them in my phone. I know some people that keep nearly everything in Evernote, but there’s something about it that I find a bit clunky, so I tend to use it sparingly. Google Tasks – One of my biggest paper wasting habits was keeping a running task-list next to my computer at work. Every morning I would sit down, look at my task list, cross off what was done and add new tasks that I thought of during my morning commute. This usually resulted in having to re-copy the task list onto a fresh sheet of paper when I was done. I still keep a running task list at my desk, but I’ve started using Google Tasks instead. This is a dead-simple web-based application for quickly adding, deleting, and organizing tasks in a simple checklist style. You can quickly move tasks up and down on the list (which I use for prioritizing), and even create sub-tasks for breaking down larger tasks into smaller pieces. Balsamiq Mockups – This is a simple and lightweight tool for creating drawings of user interfaces. It’s great for sketching out a new feature, brainstorm the layout of a interface, or even draw up a quick sequence diagram. I’m terrible at drawing, so Balsamiq Mockups not only lets me create sketches that other people can actually understand, but it’s also handy because you can upload a sketch to a common location for other team members to access. I can honestly say that using these tools (and having limited resources at home) have lead me to cut my paper usage down to virtually none. If I ever were to return to a traditional office workplace (hopefully never!) I’d try to employ as many of these applications and techniques as I could to keep paper usage low. I feel far less cluttered and far better organized now.

  • Feedback on TOC Generation Code

    - by vikramjb
    Hi All I wrote a small code to generate ToC or Hierachical Bullets like one sees in a word document. Like the following set 1. 2 3 3.1 3.1.1 4 5 and so on so forth, the code is working but I am not happy with the code I have written, I would appreciate if you guys could shed some light on how I can improve my C# code. You can download the project from Rapidshare Please do let me know if you need more info. I am making this a community wiki. private void frmMain_Load(object sender, EventArgs e) { this.EnableSubTaskButton(); } private void btnNewTask_Click(object sender, EventArgs e) { this.AddNodes(true); } private void AddNodes(bool IsParent) { TreeNode parentNode = tvToC.SelectedNode; string curNumber = "0"; if (parentNode != null) { curNumber = parentNode.Text.ToString(); } curNumber = this.getTOCReference(curNumber, IsParent); TreeNode childNode = new TreeNode(); childNode.Text = curNumber; this.tvToC.ExpandAll(); this.EnableSubTaskButton(); this.tvToC.SelectedNode = childNode; if (IsParent) { if (parentNode == null) { tvToC.Nodes.Add(childNode); } else { if (parentNode.Parent != null) { parentNode.Parent.Nodes.Add(childNode); } else { tvToC.Nodes.Add(childNode); } } } else { parentNode.Nodes.Add(childNode); } } private string getTOCReference(string curNumber, bool IsParent) { int lastnum = 0; int startnum = 0; string firsthalf = null; int dotpos = curNumber.IndexOf('.'); if (dotpos > 0) { if (IsParent) { lastnum = Convert.ToInt32(curNumber.Substring(curNumber.LastIndexOf('.') + 1)); lastnum++; firsthalf = curNumber.Substring(0, curNumber.LastIndexOf('.')); curNumber = firsthalf + "." + Convert.ToInt32(lastnum.ToString()); } else { lastnum++; curNumber = curNumber + "." + Convert.ToInt32(lastnum.ToString()); } } else { if (IsParent) { startnum = Convert.ToInt32(curNumber); startnum++; curNumber = Convert.ToString(startnum); } else { curNumber = curNumber + ".1"; } } return curNumber; } private void btnSubTask_Click(object sender, EventArgs e) { this.AddNodes(false); } private void EnableSubTaskButton() { if (tvToC.Nodes.Count == 0) { btnSubTask.Enabled = false; } else { btnSubTask.Enabled = true; } } private void btnTest1_Click(object sender, EventArgs e) { for (int i = 0; i < 100; i++) { this.AddNodes(true); } for (int i = 0; i < 5; i++) { this.AddNodes(false); } for (int i = 0; i < 5; i++) { this.AddNodes(true); } }

  • UIPageControl bug: showing one bullet first and then showing everything

    - by user313551
    I have some strange behavior using a UIPageControl: First it appears showing only one bullet, then when I move the scroll view all the bullets appear correctly. Is there something I'm missing before I add it as a subview? Here is my code imageScrollView.h : @interface ImageScrollView : UIView <UIScrollViewDelegate> { NSMutableDictionary *photos; BOOL *pageControlIsChangingPage; UIPageControl *pageControl; } @property (nonatomic, copy) NSMutableDictionary *photos; @property (nonatomic, copy) UIPageControl *pageControl; @end Here is the code for imageScrollView.m: #import "ImageScrollView.h" @implementation ImageScrollView @synthesize photos, pageControl; - (id)initWithFrame:(CGRect)frame { if ((self = [super initWithFrame:frame])) { // Initialization code NSLog(@"%@",pageControl); } return self; } - (void) drawRect:(CGRect)rect { [self removeAllSubviews]; UIScrollView *scroller = [[UIScrollView alloc] initWithFrame:CGRectMake(0,0,self.frame.size.width,self.frame.size.height)]; [scroller setDelegate:self]; [scroller setBackgroundColor:[UIColor grayColor]]; [scroller setShowsHorizontalScrollIndicator:NO]; [scroller setPagingEnabled:YES]; NSUInteger nimages = 0; CGFloat cx= 0; for (NSDictionary *myDictionaryObject in photos) { if (![myDictionaryObject isKindOfClass:[NSNull class]]) { NSString *photo =[NSString stringWithFormat:@"http://www.techbase.com.mx/blog/%@", [myDictionaryObject objectForKey:@"filepath"]]; NSDictionary *data = [myDictionaryObject objectForKey:@"data"]; UIView *imageContainer = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height - 30)]; TTImageView *imageView = [[TTImageView alloc] initWithFrame:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height - 30)]; imageView.urlPath=photo; [imageContainer addSubview:imageView]; UILabel *caption = [[UILabel alloc] initWithFrame:CGRectMake(0,imageView.frame.size.height,imageView.frame.size.width,10)]; [caption setText:[NSString stringWithFormat:@"%@",[data objectForKey:@"description"]]]; [caption setBackgroundColor:[UIColor grayColor]]; [caption setTextColor:[UIColor whiteColor]]; [caption setLineBreakMode:UILineBreakModeWordWrap]; [caption setNumberOfLines:0]; [caption sizeToFit]; [caption setFont:[UIFont fontWithName:@"Georgia" size:10.0]]; [imageContainer addSubview:caption]; CGRect rect = imageContainer.frame; rect.size.height = imageContainer.size.height; rect.size.width = imageContainer.size.width; rect.origin.x = ((scroller.frame.size.width - scroller.size.width) / 2) + cx; rect.origin.y = ((scroller.frame.size.height - scroller.size.height) / 2); imageContainer.frame=rect; [scroller addSubview:imageContainer]; [imageView release]; [imageContainer release]; [caption release]; nimages++; cx +=scroller.frame.size.width; } } [scroller setContentSize:CGSizeMake(nimages * self.frame.size.width, self.frame.size.height)]; [self addSubview:scroller]; pageControl = [[UIPageControl alloc] initWithFrame:CGRectMake(self.frame.size.width/2, self.frame.size.height -20, (self.frame.size.width/nimages)/2, 20)]; pageControl.numberOfPages=nimages; [self addSubview:pageControl]; [scroller release]; } -(void)dealloc { [pageControl release]; [super dealloc]; } -(void)scrollViewDidScroll:(UIScrollView *)_scrollView{ if(pageControlIsChangingPage){ return; } CGFloat pageWidth = _scrollView.frame.size.width; int page = floor((_scrollView.contentOffset.x - pageWidth /2) / pageWidth) + 1; pageControl.currentPage = page; } -(void)scrollViewDidEndDecelerating:(UIScrollView *)_scrollView{ pageControlIsChangingPage = NO; } @end

  • C#/.NET Little Wonders: The Useful But Overlooked Sets

    - by James Michael Hare
    Once again we consider some of the lesser known classes and keywords of C#.  Today we will be looking at two set implementations in the System.Collections.Generic namespace: HashSet<T> and SortedSet<T>.  Even though most people think of sets as mathematical constructs, they are actually very useful classes that can be used to help make your application more performant if used appropriately. A Background From Math In mathematical terms, a set is an unordered collection of unique items.  In other words, the set {2,3,5} is identical to the set {3,5,2}.  In addition, the set {2, 2, 4, 1} would be invalid because it would have a duplicate item (2).  In addition, you can perform set arithmetic on sets such as: Intersections: The intersection of two sets is the collection of elements common to both.  Example: The intersection of {1,2,5} and {2,4,9} is the set {2}. Unions: The union of two sets is the collection of unique items present in either or both set.  Example: The union of {1,2,5} and {2,4,9} is {1,2,4,5,9}. Differences: The difference of two sets is the removal of all items from the first set that are common between the sets.  Example: The difference of {1,2,5} and {2,4,9} is {1,5}. Supersets: One set is a superset of a second set if it contains all elements that are in the second set. Example: The set {1,2,5} is a superset of {1,5}. Subsets: One set is a subset of a second set if all the elements of that set are contained in the first set. Example: The set {1,5} is a subset of {1,2,5}. If We’re Not Doing Math, Why Do We Care? Now, you may be thinking: why bother with the set classes in C# if you have no need for mathematical set manipulation?  The answer is simple: they are extremely efficient ways to determine ownership in a collection. For example, let’s say you are designing an order system that tracks the price of a particular equity, and once it reaches a certain point will trigger an order.  Now, since there’s tens of thousands of equities on the markets, you don’t want to track market data for every ticker as that would be a waste of time and processing power for symbols you don’t have orders for.  Thus, we just want to subscribe to the stock symbol for an equity order only if it is a symbol we are not already subscribed to. Every time a new order comes in, we will check the list of subscriptions to see if the new order’s stock symbol is in that list.  If it is, great, we already have that market data feed!  If not, then and only then should we subscribe to the feed for that symbol. So far so good, we have a collection of symbols and we want to see if a symbol is present in that collection and if not, add it.  This really is the essence of set processing, but for the sake of comparison, let’s say you do a list instead: 1: // class that handles are order processing service 2: public sealed class OrderProcessor 3: { 4: // contains list of all symbols we are currently subscribed to 5: private readonly List<string> _subscriptions = new List<string>(); 6:  7: ... 8: } Now whenever you are adding a new order, it would look something like: 1: public PlaceOrderResponse PlaceOrder(Order newOrder) 2: { 3: // do some validation, of course... 4:  5: // check to see if already subscribed, if not add a subscription 6: if (!_subscriptions.Contains(newOrder.Symbol)) 7: { 8: // add the symbol to the list 9: _subscriptions.Add(newOrder.Symbol); 10: 11: // do whatever magic is needed to start a subscription for the symbol 12: } 13:  14: // place the order logic! 15: } What’s wrong with this?  In short: performance!  Finding an item inside a List<T> is a linear - O(n) – operation, which is not a very performant way to find if an item exists in a collection. (I used to teach algorithms and data structures in my spare time at a local university, and when you began talking about big-O notation you could immediately begin to see eyes glossing over as if it was pure, useless theory that would not apply in the real world, but I did and still do believe it is something worth understanding well to make the best choices in computer science). Let’s think about this: a linear operation means that as the number of items increases, the time that it takes to perform the operation tends to increase in a linear fashion.  Put crudely, this means if you double the collection size, you might expect the operation to take something like the order of twice as long.  Linear operations tend to be bad for performance because they mean that to perform some operation on a collection, you must potentially “visit” every item in the collection.  Consider finding an item in a List<T>: if you want to see if the list has an item, you must potentially check every item in the list before you find it or determine it’s not found. Now, we could of course sort our list and then perform a binary search on it, but sorting is typically a linear-logarithmic complexity – O(n * log n) - and could involve temporary storage.  So performing a sort after each add would probably add more time.  As an alternative, we could use a SortedList<TKey, TValue> which sorts the list on every Add(), but this has a similar level of complexity to move the items and also requires a key and value, and in our case the key is the value. This is why sets tend to be the best choice for this type of processing: they don’t rely on separate keys and values for ordering – so they save space – and they typically don’t care about ordering – so they tend to be extremely performant.  The .NET BCL (Base Class Library) has had the HashSet<T> since .NET 3.5, but at that time it did not implement the ISet<T> interface.  As of .NET 4.0, HashSet<T> implements ISet<T> and a new set, the SortedSet<T> was added that gives you a set with ordering. HashSet<T> – For Unordered Storage of Sets When used right, HashSet<T> is a beautiful collection, you can think of it as a simplified Dictionary<T,T>.  That is, a Dictionary where the TKey and TValue refer to the same object.  This is really an oversimplification, but logically it makes sense.  I’ve actually seen people code a Dictionary<T,T> where they store the same thing in the key and the value, and that’s just inefficient because of the extra storage to hold both the key and the value. As it’s name implies, the HashSet<T> uses a hashing algorithm to find the items in the set, which means it does take up some additional space, but it has lightning fast lookups!  Compare the times below between HashSet<T> and List<T>: Operation HashSet<T> List<T> Add() O(1) O(1) at end O(n) in middle Remove() O(1) O(n) Contains() O(1) O(n)   Now, these times are amortized and represent the typical case.  In the very worst case, the operations could be linear if they involve a resizing of the collection – but this is true for both the List and HashSet so that’s a less of an issue when comparing the two. The key thing to note is that in the general case, HashSet is constant time for adds, removes, and contains!  This means that no matter how large the collection is, it takes roughly the exact same amount of time to find an item or determine if it’s not in the collection.  Compare this to the List where almost any add or remove must rearrange potentially all the elements!  And to find an item in the list (if unsorted) you must search every item in the List. So as you can see, if you want to create an unordered collection and have very fast lookup and manipulation, the HashSet is a great collection. And since HashSet<T> implements ICollection<T> and IEnumerable<T>, it supports nearly all the same basic operations as the List<T> and can use the System.Linq extension methods as well. All we have to do to switch from a List<T> to a HashSet<T>  is change our declaration.  Since List and HashSet support many of the same members, chances are we won’t need to change much else. 1: public sealed class OrderProcessor 2: { 3: private readonly HashSet<string> _subscriptions = new HashSet<string>(); 4:  5: // ... 6:  7: public PlaceOrderResponse PlaceOrder(Order newOrder) 8: { 9: // do some validation, of course... 10: 11: // check to see if already subscribed, if not add a subscription 12: if (!_subscriptions.Contains(newOrder.Symbol)) 13: { 14: // add the symbol to the list 15: _subscriptions.Add(newOrder.Symbol); 16: 17: // do whatever magic is needed to start a subscription for the symbol 18: } 19: 20: // place the order logic! 21: } 22:  23: // ... 24: } 25: Notice, we didn’t change any code other than the declaration for _subscriptions to be a HashSet<T>.  Thus, we can pick up the performance improvements in this case with minimal code changes. SortedSet<T> – Ordered Storage of Sets Just like HashSet<T> is logically similar to Dictionary<T,T>, the SortedSet<T> is logically similar to the SortedDictionary<T,T>. The SortedSet can be used when you want to do set operations on a collection, but you want to maintain that collection in sorted order.  Now, this is not necessarily mathematically relevant, but if your collection needs do include order, this is the set to use. So the SortedSet seems to be implemented as a binary tree (possibly a red-black tree) internally.  Since binary trees are dynamic structures and non-contiguous (unlike List and SortedList) this means that inserts and deletes do not involve rearranging elements, or changing the linking of the nodes.  There is some overhead in keeping the nodes in order, but it is much smaller than a contiguous storage collection like a List<T>.  Let’s compare the three: Operation HashSet<T> SortedSet<T> List<T> Add() O(1) O(log n) O(1) at end O(n) in middle Remove() O(1) O(log n) O(n) Contains() O(1) O(log n) O(n)   The MSDN documentation seems to indicate that operations on SortedSet are O(1), but this seems to be inconsistent with its implementation and seems to be a documentation error.  There’s actually a separate MSDN document (here) on SortedSet that indicates that it is, in fact, logarithmic in complexity.  Let’s put it in layman’s terms: logarithmic means you can double the collection size and typically you only add a single extra “visit” to an item in the collection.  Take that in contrast to List<T>’s linear operation where if you double the size of the collection you double the “visits” to items in the collection.  This is very good performance!  It’s still not as performant as HashSet<T> where it always just visits one item (amortized), but for the addition of sorting this is a good thing. Consider the following table, now this is just illustrative data of the relative complexities, but it’s enough to get the point: Collection Size O(1) Visits O(log n) Visits O(n) Visits 1 1 1 1 10 1 4 10 100 1 7 100 1000 1 10 1000   Notice that the logarithmic – O(log n) – visit count goes up very slowly compare to the linear – O(n) – visit count.  This is because since the list is sorted, it can do one check in the middle of the list, determine which half of the collection the data is in, and discard the other half (binary search).  So, if you need your set to be sorted, you can use the SortedSet<T> just like the HashSet<T> and gain sorting for a small performance hit, but it’s still faster than a List<T>. Unique Set Operations Now, if you do want to perform more set-like operations, both implementations of ISet<T> support the following, which play back towards the mathematical set operations described before: IntersectWith() – Performs the set intersection of two sets.  Modifies the current set so that it only contains elements also in the second set. UnionWith() – Performs a set union of two sets.  Modifies the current set so it contains all elements present both in the current set and the second set. ExceptWith() – Performs a set difference of two sets.  Modifies the current set so that it removes all elements present in the second set. IsSupersetOf() – Checks if the current set is a superset of the second set. IsSubsetOf() – Checks if the current set is a subset of the second set. For more information on the set operations themselves, see the MSDN description of ISet<T> (here). What Sets Don’t Do Don’t get me wrong, sets are not silver bullets.  You don’t really want to use a set when you want separate key to value lookups, that’s what the IDictionary implementations are best for. Also sets don’t store temporal add-order.  That is, if you are adding items to the end of a list all the time, your list is ordered in terms of when items were added to it.  This is something the sets don’t do naturally (though you could use a SortedSet with an IComparer with a DateTime but that’s overkill) but List<T> can. Also, List<T> allows indexing which is a blazingly fast way to iterate through items in the collection.  Iterating over all the items in a List<T> is generally much, much faster than iterating over a set. Summary Sets are an excellent tool for maintaining a lookup table where the item is both the key and the value.  In addition, if you have need for the mathematical set operations, the C# sets support those as well.  The HashSet<T> is the set of choice if you want the fastest possible lookups but don’t care about order.  In contrast the SortedSet<T> will give you a sorted collection at a slight reduction in performance.   Technorati Tags: C#,.Net,Little Wonders,BlackRabbitCoder,ISet,HashSet,SortedSet

  • CSS Horizontal sub-menu

    - by Develman
    Hello, I am working on a horizontal CSS dropdown menu. It is still working nearly fine for IE 7, IE 8 , Firefox and Chrome. But I want to make the top <ul> to be on top level (e.g. z-index: 100). I want this because the top level <ul> has a graphical background and the dropdown is just styled with css and in the current way it is destroying the layout. HTML Code: <div id="mainMenu"> <ul> <li><a href="t1">TOP1<!--[if gt IE 6]><!--></a><!--<![endif]--> <!--[if lte IE 6]><table><tr><td><![endif]--> <ul> <li><a href="l1">LINK1</a></li> <li><a href="l2">LINK2</a></li> <li><a href="l3">LINK3</a></li> <li><a href="l4">LINK4</a></li> </ul> <!--[if lte IE 6]></td></tr></table></a><![endif]--> </li> <li class="center"><a href="t2">TOP2<!--[if gt IE 6]><!--></a><!--<![endif]--> <!--[if lte IE 6]><table><tr><td></td></tr></table></a><![endif]--></li> <li><a name="t3">TOP3<!--[if gt IE 6]><!--></a><!--<![endif]--> <!--[if lte IE 6]><table><tr><td><![endif]--> <ul class="last"> <li><a href="l5">LINK5</a></li> <li><a href="l6">LINK6</a></li> <li><a href="l7">LINK7</a></li> </ul> <!--[if lte IE 6]></td></tr></table></a><![endif]--> </li> </ul> </div> CSS Code /* style the outer div to give it width */ #mainMenu { position: absolute; margin-left: 6px; margin-top: 180px; } /* remove all the bullets, borders and padding from the default list styling */ #mainMenu ul { position: absolute; width: 494px; padding: 0; margin: 0; list-style-type: none; background: #FFF url(../images/mainMenu_bg.gif) no-repeat; } /* float the list to make it horizontal and a relative positon so that you can control the dropdown menu positon */ #mainMenu li { position: relative; float: left; padding-left: 5px; width: 160px; vertical-align: middle; text-align: left; } #mainMenu li.center { padding-left: 0px; text-align: center; } /* style the links for the top level */ #mainMenu a, #mainMenu a:visited { display: block; font: bold 12px/1em Helvetica, arial, sans-serif; color: #FFF; text-decoration: none; height: 42px; line-height: 35px; } /* hide the sub levels and give them a positon absolute so that they take up no room */ #mainMenu ul ul { visibility: hidden; position: absolute; height: 0; top: 35px; left: -5px; width: 165px; } /* style the table so that it takes no part in the layout - required for IE to work */ #mainMenu table { position: absolute; top: 0; left: 0; } /* style the second level links */ #mainMenu ul ul a, #mainMenu ul ul a:visited { width: 165px; height: 20px; line-height: 19px; font: bold 10px Helvetica, arial, sans-serif; background: #EF7D0E; color: #FFF; text-align: left; padding: 6px 0 0 5px; border-top: 1px solid #C1650B; } #mainMenu ul ul.last a, #mainMenu ul ul.last a:visited { width: 162px; } /* style the top level hover */ #mainMenu a:hover, #mainMenu ul ul a:hover{ color: #FFF; text-decoration: underline; } #mainMenu :hover > a, #mainMenu ul ul :hover > a { color: #FFF; text-decoration: underline; } /* make the second level visible when hover on first level list OR link */ #mainMenu ul li:hover ul, #mainMenu ul a:hover ul{ visibility: visible; } I have still a problem with showing the table in IE 6 but my main problem here is to show the LINK1...6 under the TOP links. I have tried many settings with z-index but nothing worked here. I hope you can help me ;)

  • Using WeakReference to resolve issue with .NET unregistered event handlers causing memory leaks.

    - by Eric
    The problem: Registered event handlers create a reference from the event to the event handler's instance. If that instance fails to unregister the event handler (via Dispose, presumably), then the instance memory will not be freed by the garbage collector. Example: class Foo { public event Action AnEvent; public void DoEvent() { if (AnEvent != null) AnEvent(); } } class Bar { public Bar(Foo l) { l.AnEvent += l_AnEvent; } void l_AnEvent() { } } If I instantiate a Foo, and pass this to a new Bar constructor, then let go of the Bar object, it will not be freed by the garbage collector because of the AnEvent registration. I consider this a memory leak, and seems just like my old C++ days. I can, of course, make Bar IDisposable, unregister the event in the Dispose() method, and make sure to call Dispose() on instances of it, but why should I have to do this? I first question why events are implemented with strong references? Why not use weak references? An event is used to abstractly notify an object of changes in another object. It seems to me that if the event handler's instance is no longer in use (i.e., there are no non-event references to the object), then any events that it is registered with should automatically be unregistered. What am I missing? I have looked at WeakEventManager. Wow, what a pain. Not only is it very difficult to use, but its documentation is inadequate (see http://msdn.microsoft.com/en-us/library/system.windows.weakeventmanager.aspx -- noticing the "Notes to Inheritors" section that has 6 vaguely described bullets). I have seen other discussions in various places, but nothing I felt I could use. I propose a simpler solution based on WeakReference, as described here. My question is: Does this not meet the requirements with significantly less complexity? To use the solution, the above code is modified as follows: class Foo { public WeakReferenceEvent AnEvent = new WeakReferenceEvent(); internal void DoEvent() { AnEvent.Invoke(); } } class Bar { public Bar(Foo l) { l.AnEvent += l_AnEvent; } void l_AnEvent() { } } Notice two things: 1. The Foo class is modified in two ways: The event is replaced with an instance of WeakReferenceEvent, shown below; and the invocation of the event is changed. 2. The Bar class is UNCHANGED. No need to subclass WeakEventManager, implement IWeakEventListener, etc. OK, so on to the implementation of WeakReferenceEvent. This is shown here. Note that it uses the generic WeakReference that I borrowed from here: http://damieng.com/blog/2006/08/01/implementingweakreferencet I had to add Equals() and GetHashCode() to his class, which I include below for reference. class WeakReferenceEvent { public static WeakReferenceEvent operator +(WeakReferenceEvent wre, Action handler) { wre._delegates.Add(new WeakReference<Action>(handler)); return wre; } public static WeakReferenceEvent operator -(WeakReferenceEvent wre, Action handler) { foreach (var del in wre._delegates) if (del.Target == handler) { wre._delegates.Remove(del); return wre; } return wre; } HashSet<WeakReference<Action>> _delegates = new HashSet<WeakReference<Action>>(); internal void Invoke() { HashSet<WeakReference<Action>> toRemove = null; foreach (var del in _delegates) { if (del.IsAlive) del.Target(); else { if (toRemove == null) toRemove = new HashSet<WeakReference<Action>>(); toRemove.Add(del); } } if (toRemove != null) foreach (var del in toRemove) _delegates.Remove(del); } } public class WeakReference<T> : IDisposable { private GCHandle handle; private bool trackResurrection; public WeakReference(T target) : this(target, false) { } public WeakReference(T target, bool trackResurrection) { this.trackResurrection = trackResurrection; this.Target = target; } ~WeakReference() { Dispose(); } public void Dispose() { handle.Free(); GC.SuppressFinalize(this); } public virtual bool IsAlive { get { return (handle.Target != null); } } public virtual bool TrackResurrection { get { return this.trackResurrection; } } public virtual T Target { get { object o = handle.Target; if ((o == null) || (!(o is T))) return default(T); else return (T)o; } set { handle = GCHandle.Alloc(value, this.trackResurrection ? GCHandleType.WeakTrackResurrection : GCHandleType.Weak); } } public override bool Equals(object obj) { var other = obj as WeakReference<T>; return other != null && Target.Equals(other.Target); } public override int GetHashCode() { return Target.GetHashCode(); } } It's functionality is trivial. I override operator + and - to get the += and -= syntactic sugar matching events. These create WeakReferences to the Action delegate. This allows the garbage collector to free the event target object (Bar in this example) when nobody else is holding on to it. In the Invoke() method, simply run through the weak references and call their Target Action. If any dead (i.e., garbage collected) references are found, remove them from the list. Of course, this only works with delegates of type Action. I tried making this generic, but ran into the missing where T : delegate in C#! As an alternative, simply modify class WeakReferenceEvent to be a WeakReferenceEvent, and replace the Action with Action. Fix the compiler errors and you have a class that can be used like so: class Foo { public WeakReferenceEvent<int> AnEvent = new WeakReferenceEvent<int>(); internal void DoEvent() { AnEvent.Invoke(5); } } Hopefully this will help someone else when they run into the mystery .NET event memory leak!

  • Data Modeling: Logical Modeling Exercise

    - by swisscheese
    In trying to learn the art of data storage I have been trying to take in as much solid information as possible. PerformanceDBA posted some really helpful tutorials/examples in the following posts among others: is my data normalized? and Relational table naming convention. I already asked a subset question of this model here. So to make sure I understood the concepts he presented and I have seen elsewhere I wanted to take things a step or two further and see if I am grasping the concepts. Hence the purpose of this post, which hopefully others can also learn from. Everything I present is conceptual to me and for learning rather than applying it in some production system. It would be cool to get some input from PerformanceDBA also since I used his models to get started, but I appreciate all input given from anyone. As I am new to databases and especially modeling I will be the first to admit that I may not always ask the right questions, explain my thoughts clearly, or use the right verbage due to lack of expertise on the subject. So please keep that in mind and feel free to steer me in the right direction if I head off track. If there is enough interest in this I would like to take this from the logical to physical phases to show the evolution of the process and share it here on Stack. I will keep this thread for the Logical Diagram though and start new one for the additional steps. For my understanding I will be building a MySQL DB in the end to run some tests and see if what I came up with actually works. Here is the list of things that I want to capture in this conceptual model. Edit for V1.2 The purpose of this is to list Bands, their members, and the Events that they will be appearing at, as well as offer music and other merchandise for sale Members will be able to match up with friends Members can write reviews on the Bands, their music, and their events. There can only be one review per member on a given item, although they can edit their reviews and history will be maintained. BandMembers will have the chance to write a single Comment on Reviews about the Band they are associated with. Collectively as a Band only one Comment is allowed per Review. Members can then rate all Reviews and Comments but only once per given instance Members can select their favorite Bands, music, Merchandise, and Events Bands, Songs, and Events will be categorized into the type of Genre that they are and then further subcategorized into a SubGenre if necessary. It is ok for a Band or Event to fall into more then one Genre/SubGenre combination. Event date, time, and location will be posted for a given band and members can show that they will be attending the Event. An Event can be comprised of more than one Band, and multiple Events can take place at a single location on the same day Every party will be tied to at least one address and address history shall be maintained. Each party could also be tied to more then one address at a time (i.e. billing, shipping, physical) There will be stored profiles for Bands, BandMembers, and general members. So there it is, maybe a bit involved but could be a great learning tool for many hopefully as the process evolves and input is given by the community. Any input? EDIT v1.1 In response to PerformanceDBA U.3) That means no merchandise other than Band merchandise in the database. Correct ? That was my original thought but you got me thinking. Maybe the site would want to sell its own merchandise or even other merchandise from the bands. Not sure a mod to make for that. Would it require an entire rework of the Catalog section or just the identifying relationship that exists with the Band? Attempted a mod to sell both complete albums or song. Either way they would both be in electronic format only available for download. That is why I listed an Album as being comprised of Songs rather then 2 separate entities. U.5) I understand what you bring up about the circular relation with Favorite. I would like to get to this “It is either one Entity with some form of differentiation (FavoriteType) which identifies its treatment” but how to is not clear to me. What am I missing here? u.6) “Business Rules This is probably the only area you are weak in.” Thanks for the honest response. I will readdress these but I hope to clear up some confusion in my head first with the responses I have posted back to you. Q.1) Yes I would like to have Accepted, Rejected, and Blocked. I am not sure what you are referring to as to how this would change the logical model? Q.2) A person does not have to be a User. They can exist only as a BandMember. Is that what you are asking? Minor Issue Zero, One, or More…Oops I admit I forgot to give this attention when building the model. I am submitting this version as is and will address in a future version. I need to read up more on Constraint Checking to make sure I am understanding things. M.4) Depends if you envision OrderPurchase in the future. Can you expand as to what you mean here? EDIT V1.2 In response to PerformanceDBA input... Lessons learned. I was mixing the concept of Identifying / Non-Identifying and Cardinality (i.e. Genre / SubGenre), and doing so inconsistently to make things worse. Associative Tables are not required in Logical Diagrams as their many-to-many relationships can be depicted and then expanded in the Physical Model. I was overlooking the Cardinality in a lot of the relationships The importance of reading through relationships using effective Verb Phrases to reassure I am modeling what I want to accomplish. U.2) In the concept of this model it is only required to track a Venue as a location for an Event. No further data needs to be collected. With that being said Events will take place on a given EventDate and will be hosted at a Venue. Venues will host multiple events and possibly multiple events on a given date. In my new model my thinking was that EventDate is already tied to Event . Therefore, Venue will not need a relationship with EventDate. The 5th and 6th bullets you have listed under U.2) leave me questioning my thinking though. Am I missing something here? U.3) Is it time to move the link between Item and Band up to Item and Party instead? With the current design I don't see a possibility to sell merchandise not tied to the band as you have brought up. U.5) I left as per your input rather than making it a discrete Supertype/Subtype Relationship as I don’t see a benefit of having that type of roll up. Additional Revisions AR.1) After going through the exercise for FavoriteItem, I feel that Item to Review requires a many-to-many relationship so that is indicated. Necessary? Ok here we go for v1.3 I took a few days on this version, going back and forth with my design. Once the logical process is complete, as I want to see if I am on the right track, I will go through in depth what I had learned and the troubles I faced as a beginner going through this process. The big point for this version was it took throwing in some Keys to help see what I was missing in the past. Going through the process of doing a matrix proved to be of great help also. Regardless of anything, if it wasn't for the input given by PerformanceDBA I would still be a lost soul wondering in the dark. Who knows my current design might reaffirm that I still am, but I have learned a lot so I am know I at least have a flashlight in my hand. At this point in time I admit that I am still confused about identifying and non-identifying relationships. In my model I had to use non-identifying relationships with non nulls just to join the relationships I wanted to model. In reading a lot on the subject there seems to be a lot of disagreement and indecisiveness on the subject so I did what I thought represented the right things in my model. When to force (identifying) and when to be free (non-identifying)? Anyone have inputs? EDIT V1.4 Ok took the V1.3 inputs and cleaned things up for this V1.4 Currently working on a V1.5 to include attributes.

  • Position:absolute

    - by Andrew
    I have I have a div called logo. I want the logo to be on top of other areas and to overlap into the the preface top of a drupal site, the logo currently sits in the header area. I looked up position absolute and I think that what I need to use but when I use position absolute the logo disappears, I can see it if I use position fixed, relative etc. I thought the logo was being hidden because I was not using a z-index but even with that I cant see the logo. What am I doing wrong? #logo { position: absolute; top: 30px; /* 30 pixels from the top of the page */ left: 80px; /* 80 pixels from the left hand side */ z-index:1099; border: 1px solid red; /* So we can see what is happening */ } Also does anyone know of a really good free online css course?
